After these works, the Florentines determined, as Giovanni Villani relates in his History, to build a principal church in their city, and to build it such that in point of greatness and magnificence there could be desired none larger or more beautiful from the industry and knowledge of men; and Arnolfo made the design and the model of the never to be sufficiently praised Church of S. Maria del Fiore, ordering that it should be all incrusted, without, with polished marbles and with the so many cornices, pilasters, columns, carved foliage, figures, and other ornaments, with which to-day it is seen brought, if not to the whole, to a great part at least of its perfection. And what was marvellous therein above everything else was this, that incorporating, besides S. Reparata, other small churches and houses that were round it, in making the site, which is most beautiful, he showed so great diligence and judgment in causing the foundations of so great a fabric to be made broad and deep, filling them with good material--namely, with gravel and lime and with great stones below--wherefore the square is still called "Lungo i Fondamenti," that they have been very well able, as is to be seen to-day, to support the weight of the great mass of the cupola which Filippo di Ser Brunellesco raised over them. The laying of such foundations for so great a church was celebrated with much solemnity, for on the day of the Nativity of Our Lady, in 1298, the first stone was laid by the Cardinal Legate of the Pope, in the presence not only of many Bishops and of all the clergy, but of the Podesta as well, the Captains, Priors, and other magistrates of the city, nay, of the whole people of Florence, calling it S. Maria del Fiore. And because it was estimated that the expenses of this fabric must be very great, as they afterwards were, there was imposed a tax at the Chamber of the Commune of four danari in the lira on everything that was put out at interest, and two soldi per head per annum; not to mention that the Pope and the Legate granted very great indulgences to those who should make them offerings thereunto. I will not forbear to say, moreover, that besides the foundations, very broad and fifteen braccia deep, much consideration was shown in making those buttresses of masonry at every angle of the eight sides, seeing that it was these afterwards that emboldened the mind of Brunellesco to superimpose a much greater weight than that which Arnolfo, perchance, had thought to impose thereon. It is said that while the two first side-doors of S. Maria del Fiore were being begun in marble Arnolfo caused some fig-leaves to be carved on a frieze, these being the arms of himself and of Maestro Lapo, his father, and that therefore it may be believed that from him the family of the Lapi had its origin, to-day a noble family in Florence. Others say, likewise, that from the descendants of Arnolfo there descended Filippo di Ser Brunellesco.
